K8BCE220/45B DC Motorized Impellers

The K8BCE220/45B is a DC motorized impeller delivering 570 CFM of airflow, engineered for flexible speed control in industrial cooling and climate management systems. Operating on a nominal 48VDC supply with an input range of 36-60VDC, this unit accommodates variable power conditions while maintaining stable performance across diverse facility environments.

This impeller features an external rotor motor design that delivers a compact footprint ideal for retrofit installations and space-limited applications. Speed control is achieved through either 0-10VDC analog signals or PWM modulation, allowing seamless integration with building automation systems and variable load requirements. The precision ball bearing motors and factory-balanced construction produce smooth, low-noise operation, while soft start circuitry minimizes inrush current and mechanical stress during startup. Locked rotor protection prevents damage if the impeller becomes obstructed, and reverse polarity protection safeguards the motor from wiring errors.

The K8BCE220/45B includes a tachometer output with open collector configuration, enabling real-time speed monitoring and diagnostic feedback within your control system. Combined with Class F thermal protection and precision engineering throughout, this DC motorized impeller provides reliable variable-speed performance for advanced cooling applications requiring dynamic control and system feedback.
